Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed December 10, 1904. Serial No. 236,376.

To all whom it may concern.-

Be it known that I, CHARLES E. SPRINGER, a citizen of the United Statesof America, and a resident of Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements inAdjustable Supports for Joists, of which the following is aspecification.

This invention relates to a leveling-support for the ends of the joistsof buildings, and has for its object to provide a simple and efficientappliance for attachment to the side or sides of the joists near theirrespective ends and by means of which the ends of the joists can beindividually and accurately adjusted so that their upper surfaces willbe on a common level and be so maintained in a certain and substantialmanner, while the whole series of joists are laid and brought to acommon level and while the wall beneath the joists is being pointed upwith mortar, cement, or the like as the final and permanent support forthe series of joists, all as will hereinafter more fully appear.

In the accompanying drawings, Figure 1 is detail longitudinal sectionalelevation at line 00 m, Fig. 2, illustrative of the present invention.Fig. 2 is a detail transverse section at line 00 a), Fig. 2.

Similar numerals of reference indicate like parts in both views.

In the setting of wood joists of buildings so that their upper surfaceswill be on a common level difiiculties and delays are met with owing toirregularities in the surface of the walls upon which the joists arelaid and which irregularities necessitate the introduction of pieces ofslate or other material beneath the individual ends of more or less ofthe joists in order to attain a common level of their upper surfaces.

The present improvement is intended to dispense with the ordinaryleveling provisions above mentioned and reduce the delays anddifliculties incident to the use of the same, while at the same timeaffording a substantial and conveniently-adjustable support for thejoists ends, and the present invention accordingly involves aconstruction of parts as follows:

1 represents counterpart pieces of plate metal constituting the presentjoist-support and adjustably secured in the manner hereinafter describedto opposite sides of a joist 2, near the end of the same. Saidsupporting pieces or plates are formed with lateral foot-flanges 3,

adapted to rest upon the surface of the building-wall 4E, and in thepreferred form of the present invention, as illustrated in Fig. 2 of thedrawings, such foot-flanges project away from each other, so as toprovide a wide hearing for the joists they are intended to support.While a pair of such supportingpieces is preferable on each joist end asaffording a very even and substantial support, the scope of the presentinvention embraces the use of a single supporting-piece at the end ofthe joist where the judgment of the builder may suggest such use.

5 represents one or more elongated slots formed in each of thesupporting-pieces 1 and adapted for the passage of the nails or screwsby which said supporting-pieces are attached to the sides of the joistsin a manner to permit of a ready and accurate vertical adjustment ofsaid supporting-pieces with relation to the joists.

In the practical use of the present improvement the supporting-pieces 1are initially secured to joist ends by nails 6, driven into the joistsmidway the height of the elongated slots aforesaid. The pieces can thenbe adj usted vertically to the desired position by blows of a hammer andfurther independent downward movement of a particular joist endprevented by nails driven into the same at the lower ends of theelongated slots. Should subsequent raising of the joist end be required,the same can be readily effected by driving additional nails through theelongated slots immediately beneath the driven nails last referred to.

While a plurality of elongated slots in each supporting-piece, as shownin Fig. 1, is the preferred means for affording a strong and substantialattachment, the scope of this part of the present invention is notnecessarily limited to such plurality of slots, and a single elongatedslot may be used in each piece when so desired, or other equivalentattachirlig means may be substituted for said slot or s ots.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is

1. An adjustable support for joist ends, the same comprising asupporting-piece attached ina vertically-adjustable manner to the sideof the joist with its lower end adapted to project below the joist toform an adjustable bearing for the same, substantially as set forth.

IIC

7 ina vertically-adjustable manner to the side of the joist with itslower end adapted to project below the joist to form an adjustablebearing for the same, substantially as set forth.

4:. The herein-described adjustable support for joist ends, the samecomprising a supporting-piece provided with a foot-flange at its lowerend and with one or more verticallyelongated slots, said piece beingattached in a vertically-adjustable manner to the side of the joist bynails passing through said slots, the lower end of said piece projectingbelow the joist to form an adjustable bearing for the same,substantially as set forth.

5. As an improved article of manufacture, an adjustable support forjoist ends, the same comprising a plate of metal formed with afoot-flange and provided with a series of vertically-elongated slotsadapted for the passage of a series of nails by Which the. support isattached to the joist end in a manner permitting vertical adjustmentbetween the parts, substantially as set forth.

Signed at Chicago, Illinois, this 18th day of November, 19042.
